阿桂天山的技术小结:Sqlalchemy+pyodbc连接MSSQL server测试

话不多说,有图有源码

1)确保本机安装了sql server对应的odbc驱动

在控制面板的管理工具中可以查：数据源(ODBC)

我这里已经安装了,如果没有安装可以自行下载安装

2)连接MsSql Server代码

# -*- coding: utf-8 -*-
__author__ = "阿桂天山"

#----------判断连接是否正常
from sqlalchemy import (Table, MetaData, create_engine,
                        Column, Integer, String, SmallInteger, DateTime, text)
from datetime import datetime
from sqlalchemy.orm import mapper, sessionmaker
from sqlalchemy.exc import OperationalError,InternalError

#----------测试连接mssqlserver
def try_linkMSSqldb(username,password,hostip,hostport,dbname):
    DRIVER = "ODBC Driver 18 for SQL Server"
    USERNAME = username 
    PSSWD = password 
    SERVERNAME = hostip 
    PORT=hostport
    INSTANCENAME = "\SQLEXPRESS"
    DB = dbname 

    engine = create_engine(f"mssql+pyodbc://{USERNAME}:{PSSWD}@{SERVERNAME}{INSTANCENAME}:{PORT}/{DB}?driver={DRIVER}&TrustServerCertificate=yes", fast_executemany=True)
    metadata = MetaData()
    try:
        metadata.reflect(schema=DB, bind=engine)
        return "连接成功!"
    except Exception as e:
        return repr(e)

#----------测试
print(try_linkMSSqldb('sa','aabbCC123xxx','127.0.0.1','1433','SQLTEST'))

最后,运行结果
